A high voltage capacitor includes a pair of capacitors; a common conductor, and a pair of individual conductors. Each of the pair of capacitors includes an element body having a columnar shape with a first direction as an axial direction, and including a first side surface and a second side surface facing away each other in a second direction orthogonal to the first direction, a first electrode disposed on the first side surface and electrically connected to a corresponding individual conductor of the pair of individual conductors; and a second electrode disposed on the second side surface and electrically connected to the common conductor. The pair of capacitors is disposed in such a way that the first electrodes face each other in the second direction. The common conductor surrounds the pair of capacitors and the pair of individual conductors when viewed from the first direction.
